摘　　要：采用电化学刻蚀法制备了合金微电极。用扫描电镜(SEM)表征了微电极的表面形貌并估计了有效半径;在室温下用电化学工作站对微电极进行循环伏安特性分析。表征结果表明:使用0.1 mol/L的KCl溶液,5 V电压条件下所制备的微电极的性能最佳,其有效半径在5 m以下;循环伏安响应曲线表明所制备电极的导电性能良好;微电极具有较好的稳定性。The fabrication of alloy microelectrodes by electrochemical-etching method is presented.The surface morphology of micro-electrodes is characterized by scanning electron microscopy（SEM） and the effective radius is estimated.Micro-electrode cyclic voltammetry analysis is performed by electrochemical workstation at room temperature.Characterization results show that the best performance of micro-electrode is reached at the conditions of 0.1 mol/L KCl reaction solution and 5 V voltage with the effective radius of 5 m or less.The cyclic voltammetry response curves show that the prepared electrode has good conductivity and good stablity
